Question

1. When do we say that a body is at rest and when do we say that it is moving?​

Answer 1

Answer:

We say that a body is at rest when it's position is not changing with time. And, we say that a body is moving when it's position changes with time.

Answer 2

Answer:

We do say a body is at rest when it does not change its position from a fixed point (which is at rest) with respect to time, even on the application of force. A body is said to be in motion when its position (from a fixed point) changes at regular or even at irregular intervals of time.
